Aplicación de tres dosis de fertilizante en el crecimiento y desarrollo de Alnus acuminata Kunth, (Aliso) en la comunidad de Tiocajas, canton Guamote, provincia de Chimborazo.

Abstract

The present research aimsto evaluate three doses of fertilization with three frequencies of application in the growth of Alnus acuminata kunth, (aliso), in Tiocajas commune, Guamote canton, province Chimborazo. Used plants and complete fertilizers with (10N – 30P – 10K) in 40g low doses, 60g medium doses and 80g high doses of nitrogen, phosphorus and potassium, applied to frequently (30, 60, and 90 days); the same when made the combination, thy used the statistical model, random block design (RBD); bi-factorial used in split up plot arrangements with three fertilizers does, three application frequency, and three repetitions like (33*3 = 27), experimental units (EU). Assessing the following variable: height, basal diameter, number of shoots and leaves per plants, at (30, 60, 90 and 120 days). In whole variables and in each period, the significant results are obtained and the most promising 80g of fertilizer (10N – 30P – 10K), frequency of application to 30 days, with an average height of 87.85 cm and an increase of 19.80 cm. In the basal diameters was average of 10.46 mm with an increase of 5.03 mm in the numbers of scoots 55.81 with an increase of 52.22 shoots and in the number of leaves with a medium of 56 leaves and an increase of 51.46 leaves per plants. It is concluded that the fertilizer (10N – 30P – 10K), in 80g high dose with application frequency 30 days faborably includes the growth and development of the alder. Being this favorable when contributing in the aforementioned variables. Key words: INORGANIC FERTILIZER, GROWTH AND DASOMETRIC DEVELOPMENT, FOREST EVALUATION.
